wind’s force. The smallest keelboats are model (sometimes radio-
controlled) sailboats, but keelboats that carry human passengers are
usually more than 20 feet (6 meters) in length.
Dinghies:Dinghies are nimble, small sailboats that are typically more
responsive than their ballasted cousins sporting keels. But watch out —
dinghies can capsize,or tip over. Instead of that ballast weight in the
keel, they have a lighter fin called a centerboard that’s retractable. The
centerboard may also be called a daggerboard if it retracts vertically
(see Figure 1-3), depending on its position and movement (or a leeboard
if it’s mounted on the side of the boat). Most dinghies range in length
from 8 to 20 feet (2.5 to 6 meters).
